Siddhartha Gautama was born a prince into a Hindu family in Nepal. His father wanted to protect his son from the suffering in the outside world, so he isolated his son in his palace. One day though, Siddhartha and his friend went outside. They saw a old man, dead man, and a sick man. Siddhartha was devastated that it could happen to him one day. He wanted to know how the meaning of life worked. When he got older he decided to leave his wife and son, because a holy man inspired him to be an ascetic, to find the meaning of life so he could end his suffering. Siddhartha went to a cave and starved himself, barely drink any water, and meditated all day long. One day a little girl gave him a bowl of rice. That action made him realize that his ways were all wrong. That happiness can be found through every day life and simple actions/the middle way. He sat down by a tree and meditated for months. All of a sudden he saw everything and how life works. He became the enlightened one (Nirvana). He did not know what to do with all of this information. Until Brahma told him to share all his new information with others. He became Buddha and taught people including priests the four noble truths, and the eight field path. Siddhartha also teaches people Dharma and Karma.
